Genealogy / Monika Pawlak. Adopted from Poland (Poznan). Help me? [6]

Hey, I'm adopted from Poznan and really would lika to have some information about my biological family. Can anyone help me?
I've tried nasza-klasa and so on.
My name when I lived in Poland (only 2 months, from December 92 to february 91) was Monika Pawlak.
And in my papers it stands that my mothers name is Agnieszka Pawlak, and my fathers name is Robert Giebocki (or something).
I had a grandpa, I think his name was Edmund Pawlak and I have a sister. But I don't think she knows that I exist.

Please, help me.
What shall I do?

Feel free to add or contact me if you have some information! SNAILZ@live.se
